FIGURE B-1. PROGRAMMING THE OUTPUT
FIGURE B-2. USING DISPLAY COMMANDS
NOTES: 1. Power supply assumed to be operating in constant voltage mode.
2. Examples below are intended only to illustrate command functions. Refer to PAR. 3.3.6 for pro-
gramming techniques to optimize performance.
OUTP ON Output enabled.
OUTP? Power supply returns “1” (output enabled).
VOLT 221;CURR 1.5E-2 Power supply output programmed to go to 221V, current limit 15mA
INIT:CONT ON Continuous triggers enabled.
INIT:CONT? Power supply returns “1.”
VOLT:TRIG 215;CURR:TRIG 3E-2 Power supply output programmed to return to 215V, current limit 30mA
upon receipt of trigger.
*TRG Power supply output returns to 215V,current limit 30mA.
VOLT 221;CURR 5E-2 Power supply output programmed to go to 221V, current limit 50mA
MEAS:VOLT? If actual value of output voltage is 220.9V, power supply
returns 2.209E+2.
MEAS:CURR? If actual value of output current is 0.0325A, power supply
returns 3.25E-2.
FUNC:MODE? Returns VOLT if power supply operating in constant voltage
mode, CURR for constant current mode.
CURR:TRIG? Returns 3E-2 (current value established by CURR:TRIG.
VOLT:TRIG? Returns 215 (voltage value established by VOLT:TRIG.
ABOR Pending trigger levels changed to 221V, 50mA (immediate values)
VOLT 277;CURR 2.5E-2 Power supply output programmed to go to 277V, 25mA
*TRG Power supply output returns to 221V, current limit 50mA.
INIT:CONT 0 Triggers disabled.
INIT:CONT? Power supply returns “0.”
OUTP OFF Output disabled.
OUTP? Returns 0 (output disabled).
MEAS:VOLT? Returns 0. (measured output voltage).
VOLT? Returns 221.(programmed output voltage)
CURR? Returns 5E-2 (programmed current 50mA)
CURR? MAX Returns 4E-1 (assuming maximum allowable current for power
supply being addressed is 400mA, i.e. BHK 500-0.4MG).
CURR? MIN Returns 0 (minimum allowable current).
CURR:PROT 3.8E-2 Current protection set to 38mA.
CURR? Returns 5E-2 (programmed current 50mA)
CURR:PROT? Returns 3.8E-2 , indicating programmed overcurrent protection
current value = 38mA.
CURR:PROT? MAX For BHK 500-0.4MG, returns 4.4E-1 (440mA, see Table 1-2).
SYST:VERS? Returns 2003.0.
DISP:CONT 0.9 Sets LCD contrast value to 0.9.
DISP:CONT? Returns 0.9.
DISP:MODE NORM Changes LCD to Normal metering mode.
DISP:MODE? Returns NORMAL.
DISP:MODE TEXT Changes LCD to Text mode.
DISP:TEXT “**BHK IS IN USE” Second line of display reads **BHK IS IN USE.
DISP:MODE? Returns “TEXT”
DISP:TEXT? Returns “**BHK IS IN USE”
